WINDOW-SASH LOCK.

Specification of Letters Patent.

Application filed November 9, 1914. Serial No. 870,952.

To all whom it may concern Be it known that I, BENJAMIN ADnLsoN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Window-Sash Locks, of which the following is a specification. 7

My invention relates to improvements in window sash locks, and more particularly to that class or type lmown as ventilating sash looks, that is to say,-a lock which is adapted to lock the upper or the lower sash of a window, or both the upper and lower sash of a window, when in a partially open position for the purposes of ventilation.

The primary object of my invention is to provide a generally improved sash fastener or look of this class, which will be exceedingly simple in construction, cheap of manufacture, efficient in use, and which may be readily and quickly attached to and detached from any ordinary window sash without the use of screws, nails, or other attaching elements, and also without the use of any tools in the application of the improved fastener or look.

A further object is the provision of a lock or fastener of this class which may be carried in the pocket or hand bag of a traveler for ready application to both the upper and lower sash of an ordinary window for looking such sash as against further opening movement when either in a fully closed or partially closed position. 7 v

A still further object is the provision of a lock or fastener of this class which will effectively cooperate with and lock the upper andlower sashin any adjusted position without in any way marring or injuring the same while in use, as well as one which will in no way interfere with the free movement of either or both sash members to closed position without first moving or readjusting the lock or fastener.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure 1, is a perspective view of the improved ventilating sash lock or fastener in its operative position 'apposition for the purposes of ventilation.

Fig. 2, a vertical sectional View of such sash members the improved lock or fastener being applied to the right hand side thereof.

Similar numerals of reference designate,

like parts throughout all the figures of the drawings. i r

The improved lock or fastener .comprises a main base plate or support 1, terminating in a verticallyextending portion 1 the latter being adapted to be interposed between the rear upper portion of the lower sash 2, and the adjacent lower front or face side of the upper sash 3, it being apparent that the parts 1, and 1 are bent at an angle to conform to the form or contour of the upper portion of the lower sash and that the dependlng or anchor portion 1*, is adapted to prevent any longitudinal movement of the plate or support 1, when the looking or latching member hereinafter described is brought into cooperative locking engagement with the upper sash.

As a means of locking the sash members 2, and 3, in any desired adjusted or opened position as against further opening movements, the base plate or support 1, is provided with hinge lugs l carrying a hingedly or pi votally mounted lever or locking member 4:, the free end of said locking member being. adapted to come into engagement with the inner lower face side of the upper sash 3, so that the locking member 4:, will have a toggle like gripping action to prevent any further relative or opening movements of either or both of the two sash members in an obvious andrwell understood manner.

If desired, lever member 4:, may be provided with an outwardly flaring or conical shaped recess to receive and contain a similarly shaped resilient gripping member ysuch as rubber, cork, or the like.

It will be observed that the lever member 4:, is formed of a single blank of sheet metal Patented Nov. 9, 1915.

the free end ofthe looking or v and is crimped longitudinally of its length to form thevertically extending sides-of the shank portion thereof to reinforce and strengthen said shank portion, one end of said lever .being bent or curled about to form a hinge lug interposed between the hinge lugs 1 of the base plate, the outer or free end of said lever being formed into a conical shaped split head (see Fig. 2) forming the outwardly flaring or conical shaped recess e, to receive and contain the similarly shaped resilient gripping member a the latter being securely retained in the socket by being securely engaged by the split head crimped or formed about the same. It will also be observedthat the locking or lever member at, in the present instance. comprises a single piece of metal bent into vertically extending sides to form the shank portion thereof and also bent at one end to form an outwardly flaring or conical shaped head e, to form a similarly shaped recess for receiving the similarly shaped resilient grip member 41 the opposite end of the locking or lever member 4, being bent or curled about to form a hinge lug interposed between the upwardly and rearwardly extending hinge lugs 1 of the base plate or support 1.

It will be apparent that the form and relative position of the toggle acting lever or locking member 4, is such with respect to the sash members and the relative movements of the latter that such sash members will be securely looked as against further opening movements in any desired adjusted positions and that either or both of said sash members may be moved to or toward closed positions without any further attention to the toggle acting or locking member 4:, the free end of the latter being adapted to freely slide against the face side of the upper sash while either or both of said sash members are being moved toward closed position.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood Having thus described one of the embodiments of my invention, what I claim and desire to secure by Letters Patent, is,-

1. In a sash look, a lever member comprising a single blank of sheet metal crimped longitudinally of its length and terminating at one end in an outwardly tiaring conical shaped split head forming a similarly shaped conical shaped socket, and

a similarly shaped sash engaging resilient member fitted in said socket and engaged by said split head.

2. In a sash lock, a lever member comprising a single blank of sheet metal bent longitudinally of its length to form vertically extending reinforcing sides and terminating at one end in a downwardly and inwardly curved hinge lug and at the other in a split head forming a socket, and a conical shaped upper sash engaging resilient member fitted in said socket and engaged by said split head.

3. In a sash lock, the combination with the upper and lower sash members of a window, and a removably mounted supporting plate provided at one edge with a depending sash engaging anchor platev interposed between the rear portion of said lower sash member and the lower face side of said upper sash member and at the other with upwardly and inwardly curved hinge lugs; of an upwardly and rearwardly extending overhanging lever comprising single blank of sheet metal bent longitudinally into vertically extending sides to form the shank portion thereof, and into a hinge lug at one end interposed between said hinge lugs of said supporting plate, the outer end of said lever terminating in a conical shaped split head forming a similarly shaped recess or socket, and a resilient conical shaped sash gripping member fitted in said socket and engaged. by said split head, said resilient sash gripping member being arranged above said anchor portion to ride upon and engage with the face side of said upper sash member upon the relative opening movements of either or both of said sash. members.

4. In a sash look, a removable supporting plate bent at one end into a depending sash engaging anchor portion adapted to be interposed between the rear upper portion. of the lower sash and the lower face side of the upper sash, said supporting plate terminating at its opposite or rear edge in upwardly and inwardly curved hinge lugs, a lever member comprising a single blank of sheet metal crimped longitudinally of its length and also bent into a hinge lug interposed between. said hinge lugs'of said base plate said lever member overhanging said supporting plate and being bent at its free end into an outwardly flaring conical shaped split head forming a similarly shaped conical shaped socket, and a conical shaped resilient member fitted. in said conical shaped socket and engaged by said split head, said resilient member normally projecting above said anchor portion in engagement with the face side of said upper sash whereby a looking action is imparted between said sash and lever members upon. the relative movements of the same.

In testimony whereof Ihave affixed my signature in presence of two witnesses.
